Meg , if you continue, you will get stuck in an endless loop with this person. He is the king of “oh yes, I totally agree EXCEPT…”
And there will always be a BUT, or a HOWEVER, or the inevitable EXCEPT..
He loves the argument, and apparently has scads of downtime with which to engage it.
Just an observation.
I almost think that the trolls who take pains to seem reasonable are worse than those who blatantly antagonize.
